looks like there's a problem with the exhaust, it's about to catch fire.

also sounds like it has a small exhaust leak

pretty typical to get manifolds glowing like that. heck my turbodiesel hits 1200 deg. f. egt daily. (i should learn to keep my foot out of it) and i'll sustain 1000 deg. (or higher) all the way up a pass.

the exhaust has vband clamps. vbands are very reliable, but do not seal perfectly, especially not that those temperatures and pressures.
